Kohler Cavata

We liked the Kohler Cavata toilet we had installed in the second floor bedroom do-over so much that I replaced the toilet on the first floor last weekend with the same model.  A little taller, a little longer and a seat that slowly lowers itself, avoiding the annoying "big bang" of the older model.  What I like the most is the innards of tank come pre-installed.  If I can install a toilet without a single leak, it must be good.
